To all -wlwm 'it may concern:

Be it known that I, GEORGE ,VVnBma subject of the King zof Great Britain and Ireland,

residing in 'Monmouth, England, have in-` vented a new and useful Tire-Carrying Rim for Vehicle-lVheels, of which the following is a speciiication.

This invention relates `tol improvements in detachable 'tire-.carrying rims of the kind l S. application Serial Number 467 ,997 December 17th 1908. The'present invention has for its princi'- pal object to provide a detachable anddivisible rim which shall be of simple and efficient constructionv and which shall be aseasy as possible to get on and oi the wheel felly all operations for this purpose being i next the body of the car, and it was neces` sary to revolve"the wheel so that each siic- .30

performed on the outside of the wheel.

' With the detachablev and divisible rims described and shown in the aforesaid application for Letters Patent and in the applica-v tion Afor Letters Patent in the United States Serial Number 471,321 January 8th 1909, in order to jack the rim on and oil'l the wheel felly the jacking bolts had to be manipu-l latedon the inside of the wheel, t'. e. the side cessive jacking bolt was brought to the lowermost or nearly to the lowermost position in order to enable the Spanner or other tool employed'to be convenientlyI applied to the bolts for turning same thus causing considlerable inconvenience and delay 1n getting the rim on and olf the wheel, further the operator had to'stoop down in order to get at .the bolts, this being particularly objectionable on muddy roads.

Athe same as in the above mentioned-prior speciiications, yet the jacking bolts and the bolts for connecting, the two parts of the' rim together are so constructedas to permit of thejacking bolts being easily manipu- .lated from the outside of the wheel fellv.

For this purposethe bolt or. bolts by whicdh `the two `parts of the rim are held together are each made'tubular or provided with a longitudinal passage', and the inner end of each of the jacking bolts is so formed that' it can be engaged by one end of 'a suitable key or tool adapted to be passed in through Aon to and pushing it o the wheel felly.

Aject-ions on the innerperiphery of the rim.

the other hollow or tubu-lar'bolt (by which t-he twoV parts of the rim are connected' together), the other end of this key or toolbeing' provided with a rectangular or other suitably shaped head' or nutadapted tobe '80 operated by means, of'an `ordinary box spanner, or other -suitable means, for the purpose ofturn/ing the said key or tool so as to turn the jacking screw in one direction or the/other for respectively moving the rim 65 The accompanying drawing illustrates the invention.

Figure 1 is a transverse section of a detachable rim constructed in accordanee'with this invention. Fig. 2 shows a form of the key or tool for operating the jacking bolts. Fig. 3 isa plan view of part of one vof the bosses or projections on vthe inner periphery of the rim. Figs. 4 and v5v are respectively an end and a side view of one of the bolts for connecting the two parts of the rim together. Figs. 6 and 7 are respectively an end view and a side View (the latter partly in section) of 4one of the jacking bolts by which the rim is, forced on to and 'oit the wheel.A Fig. 8 shows 'a form of plug or cover for the -outer 'ends of the tubular b olts that connect the two parts of the rim together. -v

Like lreference numbers indicate corresponding parts inthe several figures of the drawing.' j

1 is the permanent telly ofl the wheel the outerperiphery of which is beveled or coned, 2 the metal bonding bandv fined on the fell'y l, and 3, 3a, the two parts. of the circumferentiallydivided .tire carrying rim; 4;', 4 are the two parts of one of the bosses or pro- The part 4a isprovided -with an upward pro- 'ject-ion 5 engaging in 'a lcorrespondingly formed hole in the rim part 3a, thismethod of connectingthe bosses to the tire-carry-. ingr rim being the same as described and shown in the complete specification iiled in connection with mylU. S. application for' Letters Patent- Serial Number 467,997 December 17th, 1908.A The parts 4, Lla constituting the boss on the inner'periphery'of 4105 the tire carrying rim a1"e,boredv out to receive the bolts 7 and-8 vthe part 4 having a plain bore, while the bore of the part la is provided with la 'screw thread with which the 'threadson' the bolts 7 and 8 engage. iw

The part 4 of the boss is, through its upwardly projectingpart 9, connected to the part 3 of the rim by rivets, or otherwise as may be desired. 5 v 10- is the slotted locking plate (preferably in the form of a ring extending around the inside of the-wheel felly 1 and suitably secured'thereto) the reduced part or neck 7 a of the jacking bolt 8 engaging in the verti- 10 cal slot 10 in this plate.

11 is the head, which may be circular,-on the outer end. of the bolt 8 this head engaging on the outside of the plate 10 while the` ,shoulder at the outer end of the threaded I5 part of thevbolt 8 engages on the inside of .The bolt TK is provided with a rectangular or other suitably shaped head 12 whereby thebolt can be turned by means of a wrench or Spanner. "t

It will be understood that a desired number of the bosses consisting of the parts 4,.

4,-for example 4 or more as,may be desired,-are provided at intervals on the 2 5 vinner periphery of the tire carrying rim 3,

3, the felly 1 lbeing provided with a co1'- res onding number of transverse recesses an' the bonding band 2 with coinciding slotsl the example shown la rectangular recess 14I is provided in the inner end of the jacking bolt 8 withfwhich recess the correspondingly 4:0l formed end 15 of the key or vt'ool 1G (Fig. 2) -is adapted to beengaged,'17 being a rectangular head on the tool 16 adapted to be engagedrby va'suitable Spanner or wrench. The part 15 of the tool 16 is preferably "'beveled on its sides as indicated at 15 so as to facilitate its engagement with thel recess 14 in the bolt 8i 18 is a plug br cap adapted to close the puter end of the passage 13 through bolt 7 \this plug may be made of vulcanized fiber or other suitable material and in the example shown is adapted to be held in the passage or bore 13 by frictional engagement therewith, the plug for. this purpose being partially split as shown in Fig. 8.

18a is a head on the plug 18 the edge of which head may be milled or roughened to facilitate the withdrawal of the piugfmm the bolt 7.

If it is desiredito disconnect the part 3- of the rim from the wheel without removing the part 3,-. e. without removing the rim as a whole,-the boltsl 7 are successively turned by means of a Spanner or Wrench until their stems are out of engagement with parts 4a of the bosses on the rim whereupon the part 3 of the rim can be removed,'the heads of the bolts being on the outside of the wheel that is on the side facing away Afrom the body of the vehicle. If vit is 'de sired to remove the entire rim from the wheel the plugs or caps 18 are removed from the ends of the bolts 7 and the tool 16 is ypassed in through the passagel of each bolt success1vely,.so -that its end lsengages in the recess 14 in the respective jacking bolt 8, so thatupon turning the tool 16, for instance from left to right, the jacking bolt 8 will'be'turned so as to force the rim 3, 3-

off the wheel. To replacethe rim or to place a spare rim with a'xnew tire on the wheel the rim is slipped on to thefelly far enough for the right end of the threaded bore of the parts 4a of thel bosses on the rim to engage the inner ends of the jacking bolts whreupon the tool 16 is passed in through eac of thebolts 7 `in turn, so" that its end 15 -engages with the recess .14 inthe respe tive jacking bolts so that upon-turningr theitool lsay from right to left the rim wil be forced fully home on the coned face of t 1e bonding band on the felly 1.

What I claim as lmy invention, and desire to secure 'as Letters Patent is I1`-1 a tire carrying rim for wheels, the combination 'with the permanent telly, of a sectional detachable rim consisting of sepa rate tire engaging members, each of which is provided with a boss, one of the bosses being threaded and the other'having ay plain bere, a jacking bolt mounted at one side of the felly and engaging the threaded boss and iaving an engaging element for a tool at one end, and a fastening screw mounted at the opposite side of the felly and engaging both of said bosses, said fastening screw being hollow to permit the insertion therethrough of a tool to engage the said element at thev end of the jacking bolt.
